Applicability: Model DH/HS 125 series airplanes; as listed in British Aerospace Service Bulletin SB 57-76, dated December 31, 1991; certificated in any category.

Compliance: Required as indicated, unless accomplished previously.

To prevent loss of structural integrity and possible collapse of the main landing gear (MLG) on landing or take-off, accomplish the following:

(a) Within 12 months after the effective date of this AD, perform a one-time visual inspection to detect corrosion on the MLG support brackets, rear spar sections, inboard flap hinge arms, and associated attachment hardware, in accordance with British Aerospace Service Bulletin SB 57-76, dated December 31, 1991.

(b) If no corrosion is found on the MLG support brackets, rear spar sections, inboard flap hinge arms, and associated attachment hardware, no further action is necessary.

(c) If any corrosion is found on the MLG support brackets, rear spar sections, and inboard flap hinge arms, prior to further flight, replace any corroded parts found, or repair in a manner approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate.

(d) If corrosion is found on any associated attachment hardware that is within the limitations specified in the Structural Repair Manual (SRM) Chapter 51 10, prior to further flight, replace or repair in accordance with the SRM.

(e) If corrosion is found on any associated attachment hardware that is beyond the limitations specified in the Structural Repair Manual (SRM) Chapter 51 10, prior to further flight, replace or repair in a manner approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate.

(f) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Standardization Branch, ANM-113.

NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113.

(g) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished.

(h) The inspection shall be done in accordance with British Aerospace Service Bulletin SB 57-76, dated December 31, 1991. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51.
